Let's not forget that the earlier the car, the lighter it is!
"from what ive heard, the rule is: the newer the porsche, the better its reliability. "
Yes and no; within the same model, perhaps, but I would say a 911SC is MUCH more reliable than, say, a 924 Turbo, and a 1983 944 is most likely more reliable than a 1984 928S... and the concensus seems to be that the Carrera 3.2 is a whole hell of a lot more reliable than the 964.
"Powersteering has not been changed from the "1982" model 944s to the last 968 in 95. "
Ummm my 944 was built in May 1983 (coming up on its 20th birthday!!) and it has no power steering.
